Hello Thanks for writing to us with your health concern. The most reliable indicator for assessing the well being of a pregnancy is visualization of the fetal heartbeat. SO there is nothing to worry on that score. However, the bleeding getting heavier is worrisome. You should be resting, avoiding any kind of stress, intercourse etc. You should also be on progesterone. I hope all this is being done. If the bleeding has intensified, you should have a repeat scan done urgently. All the best Take care.
